I wasn't sure, since I never actually worked with the real hardware. I
assume the UBA on the VAX provides a "normal" UNIBUS, right? In that
case you could probably connect other "old" and "weird" devices to the
VAX. RP11 (RP01, RP02, RP03 anyone?), TA11 (TU60 DECcassette), VT11...

That TU56's were hooked up to a VAX-11/780 running VMS amuses me
greatly. And echoing Mark, yes please do provide us with the driver,
if you can.

Now, to putting DECtape on a MicroVAX... let me use a quote here:
"Science isn't about WHY. It's about WHY NOT."

Also, hmm QBUS<->UNIBUS bridges... you could stick a TC11/TU56 into a
MicroVAX 3900 or VAX 4000 Model 200.
